Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, device, vehicle, and storage medium for controlling vehicle taillights. Background Technology

[0002] Headlights are a crucial component of vehicles, primarily serving functions such as illumination and warning. With technological advancements, headlight designs have become increasingly diverse and personalized. Beyond illumination and warning, well-designed headlights can also enhance the overall aesthetics of a vehicle and its competitiveness. Taillights are another important part of the headlight system, mainly serving a warning function during driving, such as indicating the vehicle's position and braking status to vehicles behind, thereby improving driving safety. Additionally, some vehicles are equipped with a welcome mode, in which the taillights flash to signal a greeting.

[0003] However, current vehicle taillights have a relatively limited function, primarily serving as prompts and greetings. Furthermore, the greeting effect is rather monotonous, usually just flashing, and cannot adapt to different greeting signals, resulting in a poor user experience. Additionally, while various automakers offer a wide range of taillight designs, they are generally fixed in structure, meaning the taillight structure cannot deform and cannot achieve dynamic display or greeting effects, leading to a lack of overall technological and intelligent appeal in the vehicle. Summary of the Invention

[0004] The present invention aims to at least solve one of the technical problems existing in the prior art. Therefore, the object of the present invention is to provide a method, device, vehicle, and storage medium for controlling vehicle taillights.

[0005] This invention proposes a control method for vehicle taillights. The taillights include a lamp head assembly, a retractable mechanism, and a flip-up cover. The retractable mechanism drives the lamp head assembly to extend and retract. The flip-up cover is disposed on the lamp head assembly to adjust the shading area of ​​the lamp head assembly when the flip-up cover is opened or closed. The control method includes the following steps: receiving a welcome signal from the vehicle; determining the type of the welcome signal; controlling the vehicle to enter different intelligent welcome modes for taillights according to the type of the welcome signal; and controlling the lamp head assembly to form different shapes according to the different intelligent welcome modes for taillights through the retractable mechanism and the flip-up cover.

[0006] According to the vehicle taillight control method of the present invention, by receiving the vehicle's welcome signal and determining the type of the welcome signal, the vehicle is controlled to enter different taillight intelligent welcome modes according to different welcome signal types. Then, according to different taillight intelligent welcome modes, the lamp head assembly is controlled to dynamically deform to form different shapes. For example, the taillight can be extended to different positions by a telescopic mechanism, and the area of ​​the lamp head assembly can be adjusted by flipping the cover plate to dynamically change the hidden area of ​​the lamp head assembly. This enables the taillight to achieve a cool and deformable welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0007] In addition, the vehicle taillight control method according to embodiments of the present invention may also have the following additional technical features:

[0008] Furthermore, determining the type of the welcome signal includes: when a vehicle unlock signal is detected, determining the welcome signal as a first type of welcome signal; and / or when a key signal of the vehicle is detected within a preset range of the vehicle tailgate, determining the welcome signal as a second type of welcome signal; and / or when a vehicle tailgate unlock signal is detected, determining the welcome signal as a third type of welcome signal.

[0009] Furthermore, based on the type of the welcome signal, the vehicle is controlled to enter different intelligent taillight welcome modes, including: when the welcome signal is determined to be a first type of welcome signal, the vehicle is controlled to enter a first intelligent taillight welcome mode; when the welcome signal is determined to be a second type of welcome signal, the vehicle is controlled to enter a second intelligent taillight welcome mode; and when the welcome signal is determined to be a third type of welcome signal, the vehicle is controlled to enter a third intelligent taillight welcome mode.

[0010] Furthermore, under different taillight intelligent welcome modes, the retractable mechanism and the flip cover control the lamp head assembly to form different shapes, including: in the first taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to perform a first retraction action a first preset number of times to drive the flip cover to close or open, and during the execution of the first retraction action a first preset number of times, controlling the lamp head assembly to flash at a preset frequency; wherein, the first retraction action includes: the lamp head assembly extending from a preset retracted position to a first preset position at a first preset speed, and then retracting from the first preset position to the preset retracted position.

[0011] Furthermore, under different taillight intelligent welcome modes, the retractable mechanism and the flip cover control the lamp head assembly to form different shapes, including: in the second taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to perform a second retraction action a second preset number of times to drive the flip cover to close or open, and after performing the second retraction action, controlling the lamp head assembly to move to a first preset position, and during the second retraction action a second preset number of times and controlling the lamp head assembly to move to the first preset position, controlling the lamp head assembly to flash at a preset frequency; wherein, the second retraction action includes: the lamp head assembly extending from a preset retracted position to the first preset position at a second preset speed, and then retracting from the first preset position to the preset retracted position.

[0012] Furthermore, after executing the second extension action and controlling the lamp head assembly to move to the first preset position, the method further includes: acquiring the ambient light brightness; when the ambient light brightness is greater than a preset brightness threshold, controlling the lamp head assembly not to light up; and when the ambient light brightness is less than or equal to the preset brightness threshold, controlling the lamp head assembly to light up.

[0013] Furthermore, in the second taillight intelligent welcome mode, it also includes: when the key signal of the vehicle is detected to be outside the preset range of the vehicle tailgate, after a first preset time delay, controlling the retractable mechanism to drive the lamp head assembly to retract to the preset retraction position and turn off the lamp head assembly.

[0014] Furthermore, under different taillight intelligent welcome modes, the retractable mechanism and the flip cover control the lamp head assembly to form different shapes, including: in the third taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to extend to the second preset position at a third preset speed or to keep the lamp head assembly at the second preset position, and driving the flip cover to open to the first preset angle, and controlling the lamp head assembly to gradually light up to the preset target brightness according to the preset brightness increase rate, wherein the second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than or equal to the distance between the first preset position and the preset retraction position.

[0015] Furthermore, in the third taillight intelligent welcome mode, it also includes: when a vehicle tailgate locking signal is detected, controlling the retractable mechanism to drive the lamp head assembly to retract to a third preset position and drive the flip cover to be in a closed state; after a second preset time delay, controlling the retractable mechanism to drive the lamp head assembly to retract to the preset retraction position and turn off the lamp head assembly.

[0016] Furthermore, when both the second type of welcome signal and the third type of welcome signal are received simultaneously, the vehicle is first controlled to enter the second taillight intelligent welcome mode. After the second taillight intelligent mode is completed, the vehicle is controlled to enter the third taillight intelligent welcome mode.

[0017] Furthermore, the control method also includes: receiving a taillight off control command input by the user through the taillight control switch; responding to the taillight off control command, controlling the vehicle to exit the current taillight intelligent welcome mode, so as to control the flip cover to be in a closed state, and controlling the retractable mechanism to drive the lamp head assembly to retract to the preset retracted position or controlling the lamp head assembly to remain in the preset retracted position.

[0018] To address the aforementioned problems, this invention also proposes a control device for vehicle taillights. The taillight includes a lamp head assembly, a retractable mechanism, and a flip-up cover. The retractable mechanism drives the lamp head assembly to extend and retract. The flip-up cover covers the lamp head assembly to adjust the shading area of ​​the lamp head assembly when the flip-up cover is opened or closed. The control device includes: a receiving module for receiving a welcome signal from the vehicle; a determining module for determining the type of the welcome signal; and a control module for controlling the vehicle to enter different intelligent welcome modes for taillights based on the type of the welcome signal, and controlling the lamp head assembly to form different shapes according to the different intelligent welcome modes for taillights via the retractable mechanism and the flip-up cover.

[0019] According to an embodiment of the present invention, the vehicle taillight control device receives a welcome signal from the vehicle and determines the type of the welcome signal. Based on different welcome signal types, it controls the vehicle to enter different intelligent welcome modes for taillights. Furthermore, based on different intelligent welcome modes for taillights, it controls the lamp head assembly to dynamically deform to form different shapes. For example, it controls the taillight to extend and retract to different positions through a telescopic mechanism, and adjusts the occlusion area of ​​the lamp head assembly by flipping the cover plate, so that the hidden area of ​​the lamp head assembly dynamically changes. This enables the taillight to achieve a cool and transforming welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0020] To address the aforementioned problems, the present invention also proposes a vehicle comprising: a vehicle taillight control device as described in the second aspect embodiment of the present invention; or, the vehicle comprising: a processor, a memory, and a vehicle taillight control program stored in the memory and executable on the processor, wherein the vehicle taillight control program, when executed by the processor, implements the vehicle taillight control method as described in the first aspect embodiment of the present invention.

[0021] According to embodiments of the present invention, a vehicle receives a welcome signal from the vehicle and determines the type of the welcome signal. Based on different types of welcome signals, the vehicle is controlled to enter different intelligent welcome modes for taillights. Furthermore, based on different intelligent welcome modes for taillights, the taillight assembly is controlled to dynamically deform to form different shapes. For example, the taillights can be extended to different positions through a telescopic mechanism, and the area of ​​obstruction of the taillight assembly can be adjusted by flipping the cover plate, so that the hidden area of ​​the taillight assembly dynamically changes. This enables the taillights to achieve a cool and transforming welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0022] To address the aforementioned problems, the present invention also proposes a computer-readable storage medium storing a control program for a vehicle taillight. When the vehicle taillight control program is executed by a processor, it implements the vehicle taillight control method as described in the first aspect embodiment of the present invention.

[0023] According to an embodiment of the present invention, when a computer-readable storage medium storing a vehicle taillight control program thereon is executed by a processor, it receives a welcome signal from the vehicle and determines the type of the welcome signal. Based on different types of welcome signals, it controls the vehicle to enter different intelligent welcome modes for taillights. Furthermore, based on different intelligent welcome modes for taillights, it controls the lamp head assembly to dynamically deform to form different shapes. For example, it controls the taillights to extend and retract to different positions through a telescopic mechanism, and adjusts the occlusion area of ​​the lamp head assembly by flipping the cover plate, so that the hidden area of ​​the lamp head assembly dynamically changes. This enables the taillights to achieve a cool and transforming welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0046] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0047] The following is for reference. Figures 1-9 A method, apparatus, vehicle, and storage medium for controlling vehicle taillights according to embodiments of the present invention are described.

[0048] First, combined Figure 1-6 The relevant structure of the vehicle taillights involved in the embodiments of the present invention is described.

[0049] in, Figure 1 and Figure 2 The diagram illustrates the structural states of the vehicle taillights in the retracted and extended states according to an embodiment of the present invention. Figure 3 and Figure 4 An embodiment of the present invention is shown for... Figure 1-2 A schematic diagram of a drive structure for the taillight structure, namely a telescopic mechanism. Figure 5 and Figure 6 Another embodiment of the invention is shown for... Figure 1-2 Another driving structure for the taillight structure is illustrated in the diagram of another telescopic mechanism. The telescopic structure for driving the taillights involved in this embodiment of the invention can employ either of the two driving structures. That is to say, for... Figure 1 and Figure 2 The taillight structure shown can be extended or retracted by a retractable mechanism. The retractable mechanism involved in this embodiment of the invention may include two structures and their corresponding driving methods, wherein... Figure 3 and Figure 4 One type of retractable mechanism and its corresponding drive method are shown. Figure 5 and Figure 6 Another scalable mechanism and its corresponding actuator are shown.

[0050] First, combined Figure 1-4 Describe the driving structure of one type of taillight, namely a retractable mechanism. Specifically, such as... Figures 1-4As shown, in one embodiment of the present invention, the taillight 100 includes a lamp head assembly 40, a telescopic mechanism (not shown in the figure), and a flip cover (i.e., an opening and closing member 60). The telescopic mechanism is used to drive the lamp head assembly 40 to extend and retract, and the flip cover is disposed on the lamp head assembly 40 to adjust the shading area of ​​the lamp head assembly 40 when the flip cover is opened or closed. Specifically, when the flip cover is closed, the area it covers of the lamp head assembly 40 is the initial coverage area, such as the coverage area when the lamp head assembly 40 is in the retracted state, at which point only a small portion of the lamp head assembly 40 is exposed. When the flip cover is opened, the coverage area of ​​the lamp head assembly 40 varies depending on the opening angle. Specifically, the larger the opening angle, the smaller the coverage area of ​​the lamp head assembly 40, meaning more of the lamp head assembly 40 is exposed and less is hidden; conversely, the smaller the opening angle, the larger the coverage area of ​​the lamp head assembly 40, meaning less of the lamp head assembly 40 is exposed and more is hidden. Therefore, by opening or closing the flip cover, the coverage area of ​​the lamp head assembly 40 can be adjusted, causing a dynamic change in the hidden area of ​​the lamp head assembly. Furthermore, as... Figure 1 As shown, the taillight 100 also includes an outer lamp housing 10. The telescopic mechanism includes a first inner lamp sleeve 20, a drive assembly 30, and a flexible connector 50.

[0051] That is to say, in this embodiment, the taillight 100 may mainly include: an outer lamp housing 10, a first inner lamp sleeve 20, a drive assembly 30, a lamp head assembly 40, and a flexible connector 50. The first inner lamp sleeve 20 is movably disposed inside the outer lamp housing 10. The drive assembly 30 is disposed on the outer lamp housing 10 and is connected to the first inner lamp sleeve 20 in a transmission manner. The lamp head assembly 40 is movably disposed inside the first inner lamp sleeve 20. The flexible connector 50 passes through the first inner lamp sleeve 20 and is connected between the outer lamp housing 10 and the lamp head assembly 40, so that when the drive assembly 30 drives the first inner lamp sleeve 20 to extend or retract relative to the outer lamp housing 10, it drives the lamp head assembly 40 to extend or retract relative to the first inner lamp sleeve 20.

[0052] Specifically, by placing the first inner lamp sleeve 20 inside the outer lamp housing 10 and placing the lamp head assembly 40 inside the first inner lamp sleeve 20, the outer lamp housing 10 can cover and protect the first inner lamp sleeve 20 and the lamp head assembly 40, preventing the erosion of external foreign objects and the impact of external forces from damaging the structure of the lamp head assembly 40, thereby ensuring the structural reliability of the lamp head assembly 40 and ensuring the realization of the basic lighting function of the vehicle taillight 100.

[0053] Furthermore, the first inner lamp sleeve 20 is movably configured relative to the outer lamp housing 10. By mounting the drive assembly 30 on the outer lamp housing 10, the drive assembly 30 is connected to the first inner lamp sleeve 20. This allows the drive assembly 30 to drive the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. Additionally, by movably configuring the lamp head assembly 40 relative to the first inner lamp sleeve 20, a flexible connector 50 is inserted through the first inner lamp sleeve 20, connecting the outer lamp housing 10 and the lamp head assembly 40. When the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, the flexible connector 50, being a non-elastic element, does not deform. The contact area between the flexible connector 50 and the first inner lamp sleeve 20 gradually moves, thereby causing the lamp head assembly 40 to extend and retract relative to the first inner lamp sleeve 20. This enables multi-stage extension and retraction of the vehicle taillight 100, and the implementation of this multi-stage extension and retraction is simple and reliable.

[0054] In this way, the taillight 100 can have a retracted state and an extended state. When the taillight 100 is in the retracted state, the outer lamp housing 10, the first inner lamp sleeve 20, and the lamp head assembly 40 do not undergo relative displacement. When the taillight 100 is in the extended state, the first inner lamp sleeve 20 extends relative to the outer lamp housing 10, and the lamp head assembly 40 extends relative to the first inner lamp sleeve 20. This allows the user to switch the extension and retraction states of the taillight 100 according to actual needs, which can enhance the refinement and technological feel of the vehicle taillight 100 and improve the user experience.

[0055] Combination Figure 3 and Figure 4 As shown, the drive assembly 30 mainly includes a drive member 31 and a transmission member 32. The drive member 31 is disposed at the bottom of the outer lamp housing 10, and the transmission member 32 is disposed on the drive member 31. A third transmission part 221 is disposed at the bottom of the first inner lamp sleeve 20, and the transmission member 32 is in a transmission engagement with the third transmission part 221. Specifically, by disposing the drive member 31 at the bottom of the outer lamp housing 10, the drive assembly 30 can be stably installed. By disposing the transmission member 32 on the drive member 31, the power of the drive member 31 can be output through the transmission member 32. Furthermore, by disposing the third transmission part 221 at the bottom of the first inner lamp sleeve 20, and by engaging the transmission member 32 with the third transmission part 221, the power of the drive member 31 can be transmitted to the first inner lamp sleeve 20 sequentially through the transmission member 32 and the third transmission part 221, thereby driving the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. This makes the extension and retraction of the first inner lamp sleeve 20 relative to the outer lamp housing 10 simpler and more reliable.

[0056] Furthermore, combined Figure 3 and Figure 4As shown, the first inner lamp sleeve 20 mainly includes: an inner lamp sleeve body 21 and a transmission bar 22. The transmission bar 22 is disposed at the bottom of the inner lamp sleeve body 21, the lamp head assembly 40 is disposed inside the inner lamp sleeve body 21, and the transmission bar 22 is provided with a third transmission part 221. Specifically, by disposing of the transmission bar 22 at the bottom of the inner lamp sleeve body 21, disposing of the lamp head assembly 40 inside the inner lamp sleeve body 21, and providing a third transmission part 221 on the transmission bar 22, when the drive assembly 30 is disposed at the bottom of the first inner lamp sleeve 20, the drive assembly 30 can easily and quickly achieve transmission cooperation with the third transmission part 221, improving transmission efficiency. Furthermore, while ensuring the transmission cooperation between the first inner lamp sleeve 20 and the drive assembly 30, the design of the transmission bar 22 can achieve the weight reduction of the first inner lamp sleeve 20.

[0057] Combination Figure 2 and Figure 4 As shown, the flexible connector 50 is strip-shaped, and a through hole 23 is provided on the outer peripheral wall of the first inner lamp sleeve 20. The bottom wall of the through hole 23 is arc-shaped. The flexible connector 50 passes through the through hole 23 and contacts the bottom wall of the through hole 23. Specifically, by setting the flexible connector 50 as a strip and setting the bottom wall of the through hole 23 as arc-shaped, when the flexible connector 50 passes through the first inner lamp sleeve 20, the through hole 23 can accommodate the flexible connector 50, and the flexible connector 50 contacts the arc-shaped bottom wall of the through hole 23. Therefore, when the first inner lamp sleeve 20 moves relative to the outer lamp housing 10, the contact area between the flexible connector 50 and the bottom of the through hole 23 can be increased, making the movement of the flexible connector 50 relative to the through hole 23 more stable and smooth. Consequently, when the flexible connector 50 drives the lamp head assembly 40 to move relative to the first inner lamp sleeve 20, the stability and smoothness of the movement of the lamp head assembly 40 can be improved.

[0058] Combination Figure 1 and Figure 2 As shown, the vehicle taillight 100 may further include: an opening / closing member 60 (i.e., a flip cover), which is rotatably mounted on the lamp head assembly 40. The opening / closing member 60 is slidably engaged with the first inner lamp sleeve 20, and the top of the opening / closing member 60 covers a portion of the lamp head assembly 40, thereby changing the area of ​​the lamp head assembly 40 covered by the opening / closing member 60 when the lamp head assembly 40 extends or retracts relative to the first inner lamp sleeve 20. Specifically, the opening / closing member 60 is rotatably mounted on the lamp head assembly 40, and the top of the opening / closing member 60 can cover a portion of the lamp head assembly 40. By sliding the opening / closing member 60 with the first inner lamp sleeve 20, when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the first inner lamp sleeve 20 can drive the opening / closing member 60 to rotate relative to the lamp head assembly 40, thereby changing the area of ​​the lamp head assembly 40 covered by the opening / closing member 60, realizing the concealment or exposure of the lamp head assembly 40, and further enhancing the technological and refined feel of the taillight 100.

[0059] Furthermore, combined Figure 3 and Figure 4 As shown, the opening / closing component 60 mainly includes: an opening / closing piece 61 and a mating rod 62. The top of the mating rod 62 is connected to the outer edge of the opening / closing piece 61. The mating rod 62 is pivotally mounted on the lamp head assembly 40. The mating rod 62 is provided with a sliding groove 621. The first inner lamp sleeve 20 is provided with an inwardly protruding sliding part 24. The sliding part 24 is engaged in the sliding groove 621. Thus, when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the sliding part 24 on the first inner lamp sleeve 20 can slide and engage with the sliding groove 621 on the mating rod, causing the mating rod 62 to move relative to the lamp head assembly 40, thereby causing the opening / closing piece 61 to rotate relative to the lamp head assembly 40. This makes the rotation of the opening / closing component 60 relative to the lamp head assembly 40 more stable and reliable.

[0060] Furthermore, combined Figure 3 and Figure 4 As shown, the slide groove 621 can mainly include: a first groove segment 6211 and a second groove segment 6212. The extension direction of the first groove segment 6211 is the same as the extension and retraction direction of the lamp head assembly 40. The second groove segment 6212 is connected to the bottom of the first groove segment 6211, and the second groove segment 6212 extends outward in the direction of extending to the bottom. Specifically, the second groove segment 6212 is connected to the bottom of the first groove segment 6211. When the taillight 100 is in the retracted state, the sliding part 24 cooperates with the first groove segment 6211. When the taillight 100 is in the extended state, the sliding part 24 cooperates with the second groove segment 6212. By making the extension direction of the first groove segment 6211 the same as the extension and retraction direction of the lamp head assembly 40, and making the second groove segment 6212 extend outward in the direction of extending to the bottom, when the lamp head assembly 40 extends relative to the first inner lamp sleeve 20, the sliding part... 24 can first slide and engage with the first groove segment 6211. The opening and closing part 60 extends out relative to the first inner lamp sleeve 20 along with the lamp head assembly 40. Then, the sliding part 24 can slide and engage with the second groove segment 6212. The sliding part 24 drives the engaging rod 62 to rotate relative to the lamp head assembly 40, so that the opening and closing part 60 opens relative to the lamp head assembly 40. Thus, the covering area of ​​the opening and closing part 60 on the lamp head assembly 40 can be different in different states of the taillight 100, which can further enhance the exquisite and technological feel of the taillight 100.

[0061] Combination Figures 1-4As shown, there are multiple opening and closing components 60, which are spaced apart around the circumference of the lamp head assembly 40, and multiple opening and closing pieces 61 are connected sequentially in a ring. Specifically, by setting multiple opening and closing components 60 and arranging them spaced apart around the circumference of the lamp head assembly 40, and connecting them sequentially in a ring, the placement of the opening and closing components 60 conforms to the structure of the lamp head assembly 40. This allows the opening and closing components 60 to more effectively cover the area of ​​the lamp head assembly 40, further enhancing the sophistication of the taillight 100.

[0062] Combination Figure 3 and Figure 4 As shown, the lamp head assembly 40 mainly includes: a lamp head 41 and a second inner lamp sleeve 42. The second inner lamp sleeve 42 is fitted onto the lamp head 41, a flexible connector 50 is connected to the second inner lamp sleeve 42, and an opening / closing member 60 is rotatably mounted on the second inner lamp sleeve 42. Specifically, by fitting the second inner lamp sleeve 42 onto the lamp head 41, the second inner lamp sleeve 42 can be used to connect the flexible connector 50, and the opening / closing member 60 can be conveniently mounted on the lamp head assembly 40. This protects the structural stability of the lamp head 41, prevents the flexible connector 50 from being pulled, and prevents the opening / closing member 60 from damaging the structure of the lamp head 41, thereby further improving the structural reliability of the vehicle's taillight 100.

[0063] Combination Figure 3 and Figure 4 As shown, the taillight 100 of the vehicle may further include: an elastic reset member 70, with both ends of the elastic reset member 70 connected between the outer lamp housing 10 and the lamp head assembly 40. Specifically, by connecting both ends of the elastic reset member 70 between the outer lamp housing 10 and the lamp head assembly 40, when the taillight 100 is in the retracted state, the elastic reset member 70 can be in a natural state. During the process of the taillight 100 switching from the retracted state to the extended state, the elastic reset member 70 is gradually stretched. On the one hand, this can provide damping for the movement of the lamp head assembly 40, improving the movement stability of the lamp head assembly 40. On the other hand, the elastic reset member 70 can store elastic potential energy. When the taillight 100 switches from the extended state to the retracted state, the elastic reset member 70 releases the elastic potential energy, which can drive the lamp head assembly 40 to retract rapidly relative to the outer lamp housing 10, thereby further improving the reliability and stability of the vehicle's taillight 100.

[0064] Combination Figure 3 and Figure 4As shown, there are at least two flexible connectors 50, which are spaced apart on the outer periphery of the lamp head assembly 40. Specifically, the flexible connectors 50 can be set to at least two, so that when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the at least two flexible connectors 50 can simultaneously exert force on the lamp head assembly 40. Since the at least two flexible connectors 50 are spaced apart on the outer periphery of the lamp head assembly 40, the force exerted by the at least two flexible connectors 50 on the lamp head assembly 40 can be evenly distributed on the outer periphery of the lamp head assembly 40, thereby improving the stability of the lamp head assembly 40 extending or retracting relative to the first inner lamp sleeve 20 and improving the reliability of the vehicle's taillight 100.

[0065] On the other hand, combining Figure 1-2 and Figure 5-6 Describe another taillight drive structure, namely another retractable mechanism. Specifically, in conjunction with... Figure 1-2 and Figure 5-6 As shown, in another embodiment of the present invention, the taillight 100 includes a lamp head assembly 40, a telescopic mechanism (not shown in the figure), and a flip cover (i.e., an opening / closing member 60). The telescopic mechanism drives the lamp head assembly 40 to extend or retract, and the flip cover covers the lamp head assembly 40 to expose or conceal the lamp head assembly 40 when it is opened or closed. Additionally, in conjunction with... Figure 1-2 and Figure 5-6 As shown, the taillight 100 also includes an outer lamp housing 10. The telescopic mechanism includes a first inner lamp sleeve 20, a drive assembly 30, and a transmission mating component 80.

[0066] That is to say, in this embodiment, the taillight 100 may mainly include: an outer lamp housing 10, a first inner lamp sleeve 20, a drive assembly 30, a lamp head assembly 40, and a transmission coupling component 80. The first inner lamp sleeve 20 is movably disposed inside the outer lamp housing 10. The drive assembly 30 is disposed on the outer lamp housing 10 and is pulsatorically connected to the first inner lamp sleeve 20. The lamp head assembly 40 is movably disposed inside the first inner lamp sleeve 20. The transmission coupling component 80 is disposed on the first inner lamp sleeve 20. One side of the transmission coupling component 80 is pulsatorically engaged with the outer lamp housing 10, and the other side is pulsatorically engaged with the lamp head assembly 40, so that when the drive assembly 30 drives the first inner lamp sleeve 20 to extend or retract relative to the outer lamp housing 10, it drives the lamp head assembly 40 to extend or retract relative to the first inner lamp sleeve 20.

[0067] Specifically, by placing the first inner lamp sleeve 20 inside the outer lamp housing 10 and placing the lamp head assembly 40 inside the first inner lamp sleeve 20, the outer lamp housing 10 can cover and protect the first inner lamp sleeve 20 and the lamp head assembly 40, preventing the erosion of external foreign objects and the impact of external forces from damaging the structure of the lamp head assembly 40, thereby ensuring the structural reliability of the lamp head assembly 40 and ensuring the realization of the basic lighting function of the vehicle's headlights 100.

[0068] Furthermore, the first inner lamp sleeve 20 is movably configured relative to the outer lamp housing 10. By setting the drive assembly 30 on the outer lamp housing 10, the drive assembly 30 is connected to the first inner lamp sleeve 20 in a transmission manner. In this way, the drive assembly 30 can drive the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. Furthermore, by setting the transmission fitting 80 on the first inner lamp sleeve 20, one side of the transmission fitting 80 is in transmission engagement with the outer lamp housing 10, and the other side is in transmission engagement with the lamp head assembly 40. In this way, when the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, one side of the transmission fitting 80 can be in transmission engagement with the outer lamp housing 10, and the transmission fitting 80 can move relative to the outer lamp housing 10. The moving transmission fitting 80 can further be in transmission engagement with the lamp head assembly 40 on the other side, driving the lamp head assembly 40 to extend and retract relative to the first inner lamp sleeve 20. This enables multi-stage extension and retraction of the vehicle's headlight 100, and makes the implementation of multi-stage extension and retraction of the vehicle's headlight 100 simpler and more reliable.

[0069] In this way, the headlight 100 can have a retracted state and an extended state. When the headlight 100 is in the retracted state, the outer lamp housing 10, the first inner lamp sleeve 20, and the lamp head assembly 40 do not undergo relative displacement. When the headlight 100 is in the extended state, the first inner lamp sleeve 20 extends relative to the outer lamp housing 10, and the lamp head assembly 40 extends relative to the first inner lamp sleeve 20. This allows the user to switch the extension and retraction states of the headlight 100 according to actual needs, which can enhance the sophistication and technological feel of the headlight 100 and improve the user experience.

[0070] Combination Figure 5 and Figure 6 As shown, a first transmission part 11 is provided on the outer lamp housing 10, and a second transmission part 421 is provided on the lamp head assembly 40. The first transmission part 11 is located on one side of the transmission mating member 80 and is in transmission mating with the transmission mating member 80. The second transmission part 421 is located on the other side of the transmission mating member 80 and is in transmission mating with the transmission mating member 80. Specifically, by providing the first transmission part 11 on the outer lamp housing 10 and the second transmission part 421 on the lamp head assembly 40, one side of the transmission mating member 80 can be in transmission mating with the first transmission part 11, and the other side of the transmission mating member 80 can be in transmission mating with the second transmission part 421. This makes the transmission mating between the transmission mating member 80 and the outer lamp housing 10, as well as the transmission mating between the transmission mating member 80 and the lamp head assembly 40, more stable and reliable. This makes the transmission of power between the transmission mating member 80, the outer lamp housing 10, and the lamp head assembly 40 more stable and reliable, thereby further improving the stability and reliability of the more than 100-level extension and retraction of the vehicle lamp.

[0071] Furthermore, combined Figure 5 and Figure 6As shown, the transmission mating part 80 is a transmission gear, the first transmission part 11 is a first rack part, and the second transmission part 421 is a second rack part. One side of the transmission gear meshes with the first rack part so that when the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, it drives the transmission gear to rotate. The other side of the transmission gear meshes with the second rack part so as to drive the lamp head assembly 40 to extend and retract relative to the first inner lamp sleeve 20. Specifically, the transmission engagement component 80 can be configured as a transmission gear, the first transmission part 11 as a first rack part, and the second transmission part 421 as a second rack part. By engaging one side of the transmission gear with the first rack part, when the drive assembly 30 drives the first inner lamp sleeve 20 to extend or retract relative to the outer lamp housing 10, the transmission gear can rotate while following the first inner lamp sleeve 20 in a linear motion relative to the outer lamp housing 10. Furthermore, by engaging the other side of the transmission gear with the second rack part, the power of the transmission gear can be transmitted to the second rack part, converting the rotational motion of the transmission gear into the linear motion of the second rack part, thereby driving the lamp head assembly 40 to extend or retract relative to the first inner lamp sleeve 20. In this way, the transmission efficiency and transmission stability of the transmission engagement component 80 with the first transmission part 11 and the second transmission part 421 can be improved, thereby further improving the efficiency and stability of the vehicle's multi-stage extension and retraction.

[0072] Combination Figure 5 and Figure 6 As shown, a through hole 23 is provided on the side wall of the first inner lamp sleeve 20. The transmission gear is disposed in the through hole 23. At least a part of the transmission gear extends out from one side of the through hole 23 and meshes with the first rack portion. At least a part of the transmission gear extends out from the other side of the through hole 23 and meshes with the second rack portion. With this arrangement, while ensuring that both sides of the transmission gear mesh with the first rack portion and the second rack portion respectively, and that the lamp head assembly 40 can extend and retract relative to the first inner lamp sleeve 20 when the drive assembly 30 drives the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10, the through hole 23 not only facilitates the placement of the transmission gear on the first inner lamp sleeve 20, but also accommodates at least a part of the transmission gear. This avoids the transmission gear occupying too much volume in the vehicle lamp 100 and improves the structural compactness of the vehicle lamp 100.

[0073] Combination Figure 5 and Figure 6As shown, there are at least two transmission coupling components 80, which are spaced apart on the circumferential sidewall of the first inner lamp sleeve 20. Specifically, by setting at least two transmission coupling components 80, at least two transmission coupling components 80 can simultaneously engage with the lamp head assembly 40 to transmit power to the lamp head assembly 40. Furthermore, by spaced apart on the circumferential sidewall of the first inner lamp sleeve 20, the power transmitted to the lamp head assembly 40 by the at least two transmission coupling components 80 can be distributed more evenly, thereby further improving the stability and reliability of the extension and retraction of the lamp head assembly 40 relative to the first inner lamp sleeve 20, and further improving the reliability of the vehicle lamp 100.

[0074] Combination Figure 5 and Figure 6 As shown, the drive assembly 30 mainly includes a drive member 31 and a transmission member 32. The drive member 31 is disposed at the bottom of the outer lamp housing 10, and the transmission member 32 is disposed on the drive member 31. A third transmission part 221 is disposed at the bottom of the first inner lamp sleeve 20, and the transmission member 32 is in a transmission engagement with the third transmission part 221. Specifically, by disposing the drive member 31 at the bottom of the outer lamp housing 10, the drive assembly 30 can be stably installed. By disposing the transmission member 32 on the drive member 31, the power of the drive member 31 can be output through the transmission member 32. Furthermore, by disposing the third transmission part 221 at the bottom of the first inner lamp sleeve 20, and by engaging the transmission member 32 with the third transmission part 221, the power of the drive member 31 can be transmitted to the first inner lamp sleeve 20 sequentially through the transmission member 32 and the transmission part, thereby driving the first inner lamp sleeve 20 to extend and retract relative to the outer lamp housing 10. This makes the extension and retraction of the first inner lamp sleeve 20 relative to the outer lamp housing 10 simpler and more reliable.

[0075] Furthermore, combined Figure 5 and Figure 6 As shown, the first inner lamp sleeve 20 mainly includes: an inner lamp sleeve body 21 and a transmission bar 22. The transmission bar 22 is disposed at the bottom of the inner lamp sleeve body 21, the lamp head assembly 40 is disposed inside the inner lamp sleeve body 21, and the transmission bar 22 is provided with a third transmission part 221. Specifically, by disposing of the transmission bar 22 at the bottom of the inner lamp sleeve body 21, disposing of the lamp head assembly 40 inside the inner lamp sleeve body 21, and providing a third transmission part 221 on the transmission bar 22, when the drive assembly 30 is disposed at the bottom of the first inner lamp sleeve 20, the drive assembly 30 can easily and quickly achieve transmission cooperation with the third transmission part 221, improving transmission efficiency. Furthermore, while ensuring the transmission cooperation between the first inner lamp sleeve 20 and the drive assembly 30, the design of the transmission bar 22 can achieve the weight reduction of the first inner lamp sleeve 20.

[0076] Combination Figure 1-2 and Figure 5-6As shown, the vehicle headlight 100 may further include: an opening / closing member 60, which is rotatably mounted on the headlight assembly 40. The opening / closing member 60 is slidably engaged with the first inner lamp sleeve 20. The top of the opening / closing member 60 covers a portion of the headlight assembly 40, thereby changing the area of ​​the headlight assembly 40 covered by the opening / closing member 60 when the headlight assembly 40 extends or retracts relative to the first inner lamp sleeve 20. Specifically, the opening / closing member 60 is rotatably mounted on the headlight assembly 40, and the top of the opening / closing member 60 can cover a portion of the headlight assembly 40. By sliding the opening / closing member 60 with the first inner lamp sleeve 20, when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the first inner lamp sleeve 20 can drive the opening / closing member 60 to rotate relative to the headlight assembly 40, thereby changing the area of ​​the headlight assembly 40 covered by the opening / closing member 60. This allows for the concealment or exposure of the headlight assembly 40, enabling the transformation of the headlight 100 and further enhancing its technological and sophisticated appearance.

[0077] Combination Figure 5 and Figure 6 As shown, the opening / closing component 60 mainly includes: an opening / closing piece 61 and a mating rod 62. The top of the mating rod 62 is connected to the outer edge of the opening / closing piece 61. The mating rod 62 is pivotally mounted on the lamp head assembly 40. The mating rod 62 is provided with a sliding groove 621. The first inner lamp sleeve 20 is provided with an inwardly protruding sliding part 24. The sliding part 24 is engaged in the sliding groove 621. Thus, when the first inner lamp sleeve 20 extends or retracts relative to the outer lamp housing 10, the sliding part 24 on the first inner lamp sleeve 20 can slide and engage with the sliding groove 621 on the mating rod, causing the mating rod 62 to move relative to the lamp head assembly 40, thereby causing the opening / closing piece 61 to rotate relative to the lamp head assembly 40. This makes the rotation of the opening / closing component 60 relative to the lamp head assembly 40 more stable and reliable.

[0078] Furthermore, combined Figure 5 and Figure 6As shown, the slide 621 can mainly include: a first groove segment 6211 and a second groove segment 6212. The extension direction of the first groove segment 6211 is the same as the extension and retraction direction of the lamp head assembly 40. The second groove segment 6212 is connected to the bottom of the first groove segment 6211, and the second groove segment 6212 extends outward in the direction of extending to the bottom. Specifically, the second groove segment 6212 is connected to the bottom of the first groove segment 6211. When the vehicle lamp 100 is in the retracted state, the sliding part 24 cooperates with the first groove segment 6211. When the vehicle lamp 100 is in the extended state, the sliding part 24 cooperates with the second groove segment 6212. By making the extension direction of the first groove segment 6211 the same as the extension and retraction direction of the lamp head assembly 40, and making the second groove segment 6212 extend outward in the direction of extending to the bottom, when the lamp head assembly 40 extends relative to the first inner lamp sleeve 20, the sliding part 24 can first cooperate with the first groove segment 6211. With mutual sliding cooperation, the opening and closing part 60 extends out relative to the first inner lamp sleeve 20 along with the lamp head assembly 40. Then, the sliding part 24 can slide and cooperate with the second groove segment 6212. The sliding part 24 drives the cooperating rod 62 to rotate relative to the lamp head assembly 40. At the same time as the opening and closing part 60 extends out relative to the first inner lamp sleeve 20 along with the lamp head assembly 40, the opening and closing part 60 opens relative to the lamp head assembly 40. Thus, the coverage area of ​​the opening and closing part 60 on the lamp head assembly 40 can be different in different states of the vehicle light 100, which can further enhance the refinement and technological feel of the vehicle light 100.

[0079] Combination Figure 1 and Figure 2 As shown, there are multiple opening and closing components 60, which are spaced apart around the circumference of the lamp head assembly 40, and multiple opening and closing pieces 61 are connected sequentially in a ring. Specifically, by setting multiple opening and closing components 60 and arranging them spaced apart around the circumference of the lamp head assembly 40, and connecting them sequentially in a ring, the placement of the opening and closing components 60 conforms to the structure of the lamp head assembly 40. This allows the opening and closing components 60 to more effectively cover the area of ​​the lamp head assembly 40, further enhancing the sophistication of the vehicle headlight 100.

[0080] Furthermore, combined Figure 5 and Figure 6 As shown, the lamp head assembly 40 mainly includes: a lamp head 41 and a second inner lamp sleeve 42. The second inner lamp sleeve 42 is fitted onto the lamp head 41, a second transmission part 421 is disposed on the second inner lamp sleeve 42, and an opening / closing member 60 is rotatably disposed on the second inner lamp sleeve 42. Specifically, by fitting the second inner lamp sleeve 42 onto the lamp head 41, the second inner lamp sleeve 42 can be used for transmission engagement with the transmission engagement member 80, and the opening / closing member 60 can be conveniently disposed on the lamp head assembly 40, thereby protecting the structure of the lamp head 41, improving the structural stability of the lamp head 41, and further improving the structural reliability of the vehicle lamp 100.

[0081] Based on the above description of the structure of the taillight 100 and any one of the drive structures (i.e., telescopic mechanisms) used to drive the two types of taillights, the following combines... Figure 7-9 This invention describes a method for controlling a vehicle taillight, a control device, a vehicle, and a storage medium, wherein the vehicle taillight is, for example, the taillight 100 described in the above embodiments.

[0082] Figure 7 This is a flowchart of a vehicle taillight control method according to an embodiment of the present invention. As mentioned above, the vehicle taillight includes a lamp head assembly, a telescopic mechanism, and a flip-up cover. The telescopic mechanism drives the lamp head assembly to extend and retract, and the flip-up cover covers the lamp head assembly to adjust the area of ​​obstruction to the lamp head assembly when the flip-up cover is opened or closed. As mentioned above, the opening and closing process of the flip-up cover is linked to the action of the telescopic mechanism. That is, when the telescopic mechanism operates in different positions, the state of the flip-up cover can be adjusted accordingly, driving the flip-up cover to close or controlling its opening angle. Further details are omitted here. In other words, the extension and retraction of the telescopic mechanism and the flip-up action of the cover are linked. The opening and closing of the flip-up cover can be achieved by relying on the linkage of the two, thus eliminating the need for separate control of the flip-up cover and saving the cost of separate control. Based on this, as... Figure 7 As shown, a method for controlling vehicle taillights according to an embodiment of the present invention specifically includes the following steps:

[0083] Step S1: Receive the vehicle's welcome signal.

[0084] In specific examples, the vehicle's welcome signal may be a signal sent after the vehicle's configured welcome mode is triggered and activated. Specifically, for example, but not limited to, activating the vehicle's welcome mode when the vehicle is unlocked, thereby emitting a welcome signal corresponding to the vehicle unlocking; or, activating the vehicle's welcome mode when the car key approaches the vehicle and enters a certain range (e.g., within 1 meter) of the vehicle's tailgate, thereby emitting a welcome signal corresponding to the car key approaching the tailgate; or, activating the vehicle's welcome mode when the user opens the tailgate, such as when the user opens the vehicle's tailgate manually or by kicking it, thereby emitting a welcome signal corresponding to the tailgate opening.

[0085] Step S2: Determine the type of welcoming signal.

[0086] Specifically, after receiving a welcome signal, the type of welcome signal is determined, which can be determined by the activation method of the welcome mode. For example, if the vehicle's welcome mode is activated by unlocking the vehicle, the welcome signal is determined to be the one corresponding to vehicle unlocking; or, if the vehicle's welcome mode is activated by detecting the key, such as when the key is detected approaching the vehicle and entering within a certain range (e.g., within 1 meter) of the tailgate, the welcome signal is determined to be the one corresponding to the key approaching the tailgate; or, if the vehicle's welcome mode is activated by unlocking the tailgate, such as when the user manually or by kicking the tailgate, the welcome signal is determined to be the one corresponding to the tailgate opening.

[0087] Step S3: Based on the type of welcome signal, control the vehicle to enter different taillight intelligent welcome modes. Based on different taillight intelligent welcome modes, control the lamp head assembly to form different shapes through the retractable mechanism and the flip cover.

[0088] Specifically, after determining the type of welcome signal, the vehicle is controlled to enter a corresponding intelligent welcome mode for the taillights based on the type of welcome signal. This allows the taillight assembly to take on different shapes through a retractable mechanism and a flip-up cover, depending on the taillight's intelligent welcome mode. For example, by controlling the retractable mechanism, the taillight assembly can be extended and retracted to different positions, thus changing its structural shape. By controlling the opening and closing of the flip-up cover, the area obscured by the taillight assembly is adjusted, thereby adjusting the size of the exposed and hidden areas of the taillight assembly, and thus changing its display shape. In other words, different intelligent welcome modes are entered for different types of welcome signals, corresponding to different taillight welcome control strategies, resulting in different taillight shapes. This achieves diversified taillight welcome functions and display effects, enriching the vehicle's welcome capabilities, enhancing its intelligence and technological feel, and improving the user experience.

[0089] Specifically, the specific structure and working principle of the telescopic mechanism and the flip cover, as well as the specific implementation process of controlling the telescopic mechanism to drive the lamp head assembly to extend and retract, and controlling the flip cover to adjust the shading area of ​​the lamp head assembly, can be found in the previous text and will not be repeated here.

[0090] Therefore, the vehicle taillight control method according to the present invention receives the vehicle's welcome signal and determines the type of the welcome signal. Based on different welcome signal types, the vehicle is controlled to enter different taillight intelligent welcome modes. Then, based on different taillight intelligent welcome modes, the lamp head assembly is controlled to dynamically deform to form different shapes. For example, the taillight can be extended to different positions through a telescopic mechanism, and the area of ​​obstruction of the lamp head assembly can be adjusted by flipping the cover plate, so that the hidden area of ​​the lamp head assembly dynamically changes. This enables the taillight to achieve a cool and deformable welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0091] In one embodiment of the present invention, step S2, determining the type of the welcome signal, includes: when a vehicle unlocking signal is detected, determining the welcome signal as a first type of welcome signal; and / or when a key signal of the vehicle is detected within a preset range of the vehicle tailgate, determining the welcome signal as a second type of welcome signal; and / or when a vehicle tailgate unlocking signal is detected, determining the welcome signal as a third type of welcome signal.

[0092] Specifically, the type of welcome signal can be determined by the activation method of the welcome mode. For example, unlocking the vehicle generates a vehicle unlock signal. When this signal is detected, the vehicle's welcome mode is activated, emitting a first-type welcome signal, corresponding to unlocking the vehicle. When the car key approaches the vehicle, such as entering a preset range (e.g., 1 or 2 meters) from the tailgate, the vehicle senses the key signal and activates its welcome mode, emitting a second-type welcome signal, corresponding to the key approaching the tailgate. When the tailgate is unlocked, such as when the user opens it manually or by kicking it, a tailgate unlock signal is generated. When this signal is detected, the welcome mode is activated, emitting a third-type welcome signal, corresponding to the tailgate opening.

[0093] In one embodiment of the present invention, step S3, controlling the vehicle to enter different taillight intelligent welcome modes according to the type of welcome signal, includes: when the welcome signal is determined to be a first type of welcome signal, controlling the vehicle to enter a first taillight intelligent welcome mode; when the welcome signal is determined to be a second type of welcome signal, controlling the vehicle to enter a second taillight intelligent welcome mode; and when the welcome signal is determined to be a third type of welcome signal, controlling the vehicle to enter a third taillight intelligent welcome mode.

[0094] Specifically, when the welcome signal is determined to be a first type of welcome signal, corresponding to the vehicle unlocking welcome signal, the vehicle is controlled to enter the first taillight intelligent welcome mode, which corresponds to the taillight intelligent welcome mode activated by unlocking the vehicle. When the welcome signal is determined to be a second type of welcome signal, corresponding to the car key approaching the tailgate welcome signal, the vehicle is controlled to enter the second taillight intelligent welcome mode, which corresponds to the taillight intelligent welcome mode activated by approaching the tailgate. When the welcome signal is determined to be a third type of welcome signal, corresponding to the tailgate opening welcome signal, the vehicle is controlled to enter the third taillight intelligent welcome mode, which corresponds to the taillight intelligent welcome mode activated by unlocking (or opening) the tailgate.

[0095] Therefore, for different types of welcome signals, the vehicle is controlled to enter different intelligent taillight welcome modes, and different taillight welcome control strategies are executed accordingly, so that the taillights can display different forms, thereby realizing diversified taillight welcome functions and taillight display effects, enriching the vehicle's welcome functions, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0096] In one embodiment of the present invention, under different taillight intelligent welcome modes, the lamp head assembly is controlled to form different shapes by means of a retractable mechanism and a flip cover. Specifically, in the first taillight intelligent welcome mode, the retractable mechanism is controlled to drive the lamp head assembly to perform a first retraction action a first preset number of times to drive the flip cover to close or open, and during the execution of the first retraction action a first preset number of times, the lamp head assembly is controlled to flash at a preset frequency; wherein, the first retraction action includes: the lamp head assembly extends from a preset retractable position to a first preset position at a first preset speed, and then retracts from the first preset position to the preset retractable position.

[0097] In a specific embodiment, the first preset speed is a pre-set speed value, which can be set according to actual needs. The setting is based on the speed at which the lamp head assembly performs the first extension / retraction action. That is, when the lamp head assembly is driven to extend / retract at the first preset speed, it is considered that the lamp head assembly is performing rapid extension / retraction. Furthermore, when the retractable mechanism drives the lamp head assembly to extend from a preset retracted position to a first preset position at the first preset speed, and then retracts from the first preset position to the preset retracted position, it is considered that the lamp head assembly has rapidly performed one first extension / retraction action.

[0098] The first preset number of times is a pre-set value, which can be set according to actual needs. In specific embodiments, the first preset number of times can be 1 time, 2 times, 3 times or more, which will not be listed in detail here.

[0099] The preset frequency is a pre-set frequency value that can be set according to actual needs, and it is used to control the blinking speed of the indicator light head assembly. A larger preset frequency value corresponds to a faster blinking speed of the indicator light head assembly, while a smaller preset frequency value corresponds to a slower blinking speed.

[0100] That is, when entering the first taillight intelligent welcome mode, which corresponds to the taillight intelligent welcome mode activated by unlocking the vehicle, the retractable mechanism drives the lamp head assembly to quickly perform a first preset number of retraction actions (e.g., 2 times) to drive the flip cover to close or open, thereby covering most, a small portion, or none of the lamp head assembly, achieving a combination of mostly hidden, partially hidden, and maximum exposure of the taillights. During the 2 retraction actions, the lamp head assembly flashes at a preset frequency. The first retraction action includes: the lamp head assembly extending from a preset retracted position to a preset position at a first preset speed, and then retracting from the preset position to the preset retracted position. The preset retracted position is the position corresponding to the lamp head assembly in the retracted state or the limit position to which the lamp head assembly can retract. The first preset position is a pre-set position, which can be set to the 1st, 2nd, or 3rd position in the lamp head assembly's retraction path. The positions corresponding to the first, second, and third gears are located on the same side of the preset recovery position, and the distance between the position corresponding to the second gear and the preset recovery position is greater than the distance between the position corresponding to the first gear and the preset recovery position, and the distance between the position corresponding to the third gear and the preset recovery position is greater than the distance between the position corresponding to the second gear and the preset recovery position. The opening and closing of the flip cover can be controlled according to a first preset position. Specifically, when the first preset position is the position corresponding to the first gear, the telescopic mechanism drives the flip cover to be in the closed state, so as to cover or hide most of the area of ​​the lamp head assembly, only exposing a small part of the front part of the lamp head assembly, that is, the initial exposed part when in the retracted state; when the first preset position is the position corresponding to the second gear, the telescopic mechanism drives the flip cover to partially open, such as opening it to 7 degrees, so that the flip cover covers a small part of the area of ​​the lamp head assembly, exposing most of the area of ​​the lamp head assembly, thus partially hiding the taillight; when the first preset position is the position corresponding to the third gear, the telescopic mechanism drives the flip cover to fully open, such as opening it to 12.5 degrees, so that the flip cover no longer covers the lamp head assembly, allowing the lamp head assembly to be exposed to the maximum extent.

[0101] In a specific example, when the taillight is in the retracted state, it is at a preset retracted position, where it has retracted to its limit and cannot retract further. The taillight can extend from the preset retracted position along a set extension direction to its maximum extension position, at which point it cannot extend any further. It can then retract in a retraction direction opposite to the extension direction, reaching the preset retracted position where it cannot retract any further. The area between the preset retracted position and the maximum extension position constitutes the maximum extension or maximum retraction stroke of the taillight. In the specific example, the position corresponding to the taillight being extended to the first position corresponds to one-third of the maximum extension stroke, and at this time, the flip cover is closed to obscure or hide most of the lamp head assembly, exposing only a small portion of the front section of the lamp head assembly. When the taillights are extended to the second position, they correspond to two-thirds of their maximum extension range. At this point, the flip cover is partially open, such as at a 7-degree angle, thus partially obscuring the headlight assembly and revealing most of it. When the taillights are extended to the third position, they correspond to their maximum extension range. At this point, the flip cover is fully open, such as at a 12.5-degree angle, and no longer obscures the headlight assembly, maximizing its visibility.

[0102] In a specific embodiment, the first preset number of times is, for example, 2 times, and the first preset position is, for example, the position corresponding to the first gear. Specifically, when entering the first taillight intelligent welcome mode, that is, the taillight intelligent welcome mode corresponding to the taillight intelligent welcome mode activated by unlocking the vehicle, the retractable mechanism is controlled to drive the lamp head assembly to automatically and quickly extend and retract twice between the preset retraction position and the first gear, while the lamp head assembly is controlled to flash at a preset frequency.

[0103] In one embodiment of the present invention, under different taillight intelligent welcome modes, the lamp head assembly is controlled to form different shapes by means of a retractable mechanism and a flip cover. This includes: in the second taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to perform a second retraction action a second preset number of times to drive the flip cover to close or open; and after performing the second retraction action, controlling the lamp head assembly to move to a first preset position; and during the execution of the second retraction action a second preset number of times and the control of the lamp head assembly to move to the first preset position, controlling the lamp head assembly to flash at a preset frequency; wherein the second retraction action includes: the lamp head assembly extending from a preset retractable position to the first preset position at a second preset speed, and then retracting from the first preset position to the preset retractable position.

[0104] In a specific embodiment, the second preset speed is a pre-set speed value, which can be set according to actual needs. The setting is based on the speed at which the indicator light head assembly performs the second extension / retraction action. That is, when the indicator light head assembly is driven to extend / retract at the second preset speed, it is considered that the indicator light head assembly is performing rapid extension / retraction. Furthermore, when the retractable mechanism drives the indicator light head assembly to extend from a preset retracted position to a first preset position at the second preset speed, and then retracts from the first preset position to the preset retracted position, it is considered that the indicator light head assembly has rapidly performed one second extension / retraction action. In a specific example, the first preset speed and the second preset speed can be the same or different.

[0105] The second preset number of times is a pre-set value, which can be set according to actual needs. In specific embodiments, the second preset number of times can be 1 time, 2 times, 3 times or more, which will not be listed in detail here.

[0106] The preset frequency is a pre-set frequency value that can be set according to actual needs, and it is used to control the blinking speed of the indicator light head assembly. A larger preset frequency value corresponds to a faster blinking speed of the indicator light head assembly, while a smaller preset frequency value corresponds to a slower blinking speed.

[0107] That is, when entering the second taillight intelligent welcome mode, which corresponds to activating the welcome mode by bringing the car key close to the tailgate, the retractable mechanism drives the lamp head assembly to quickly perform a second retraction action a second preset number of times (e.g., 2 times) to drive the flip cover to close or open, thereby covering most, a small portion, or not covering the lamp head assembly, achieving a combination of mostly concealing, partially concealing, and maximizing the visibility of the taillights. After completing the second retraction action, the lamp head assembly is then controlled to move to a first preset position. During the execution of the two second retraction actions and the movement of the lamp head assembly to the first preset position, the lamp head assembly is controlled to flash at a preset frequency. The second retraction action includes: the lamp head assembly extending rapidly from a preset retracted position to the first preset position at a second preset speed, and then retracting from the first preset position to the preset retracted position. The preset retracted position is the position corresponding to the lamp head assembly in the retracted state or the limit position to which the lamp head assembly can retract. The first preset position is a pre-set gear position, which can be set to the 1st, 2nd, or 3rd gear position in the lamp head assembly extension path. The positions corresponding to the 1st, 2nd, and 3rd gear positions are located on the same side of the preset retraction position, and the distance between the position corresponding to the 2nd gear position and the preset retraction position is greater than the distance between the position corresponding to the 1st gear position and the preset retraction position, and the distance between the position corresponding to the 3rd gear position and the preset retraction position is greater than the distance between the position corresponding to the 2nd gear position and the preset retraction position. The opening and closing of the flip cover can be controlled according to a first preset position. Specifically, when the first preset position is the position corresponding to the first gear, the telescopic mechanism drives the flip cover to be in the closed state, so as to cover or hide most of the area of ​​the lamp head assembly, only exposing a small part of the front part of the lamp head assembly, that is, the initial exposed part when in the retracted state; when the first preset position is the position corresponding to the second gear, the telescopic mechanism drives the flip cover to partially open, such as opening it to 7 degrees, so that the flip cover covers a small part of the area of ​​the lamp head assembly, exposing most of the area of ​​the lamp head assembly, thus partially hiding the taillight; when the first preset position is the position corresponding to the third gear, the telescopic mechanism drives the flip cover to fully open, such as opening it to 12.5 degrees, so that the flip cover no longer covers the lamp head assembly, allowing the lamp head assembly to be exposed to the maximum extent.

[0108] In a specific embodiment, the second preset number of times is, for example, 2 times, and the first preset position is, for example, the position corresponding to the first gear. Specifically, when entering the second taillight intelligent welcome mode, that is, the taillight intelligent welcome mode when the welcome mode is activated by bringing the car key close to the tailgate, the retractable mechanism is controlled to drive the lamp head assembly to automatically and quickly extend and retract twice between the preset retraction position and the first gear, and then drive the lamp head assembly to move to the first gear and stay in the first gear. At the same time, during the operation, the lamp head assembly is controlled to flash at a preset frequency.

[0109] In one embodiment of the present invention, the retractable mechanism is controlled to drive the lamp head assembly to perform a second retractable action a second preset number of times to drive the flip cover to close or open, and after the second retractable action is completed, the lamp head assembly is controlled to move to a first preset position, and the method further includes: acquiring ambient light brightness; when the ambient light brightness is greater than a preset brightness threshold, controlling the lamp head assembly not to light up; when the ambient light brightness is less than or equal to the preset brightness threshold, controlling the lamp head assembly to light up.

[0110] Specifically, in the second taillight welcome mode, the retractable mechanism drives the lamp head assembly to automatically and rapidly extend and retract between a preset retracted position and a first preset position a second preset number of times. After the lamp head assembly moves to the first preset position, it further acquires the ambient light brightness to determine whether it is daytime, nighttime, or a dimly lit location. When the ambient light brightness is greater than a preset brightness threshold, it is considered to be daytime with clear visibility, and the lamp head assembly is kept off to save energy. When the ambient light brightness is less than or equal to the preset brightness threshold, it is considered to be nighttime or a dimly lit location, and the lamp head assembly is turned on to better showcase the dynamic transformation and welcome effect of the taillights, while also serving as a warning.

[0111] In one embodiment of the present invention, in the second taillight intelligent welcome mode, the method further includes: when the key signal of the vehicle is detected to be outside the preset range of the vehicle tailgate, after a first preset time delay, controlling the retractable mechanism to drive the lamp head assembly to retract to a preset retraction position and turn off the lamp head assembly.

[0112] Specifically, after entering the intelligent welcome mode for the second taillight, if the vehicle's key signal is detected to be outside the preset range of the tailgate (i.e., the key is far from the vehicle), it is assumed that the owner has left the vehicle, and the intelligent welcome mode for the second taillight is exited, thus turning off the taillight welcome function. When the key is detected to be out of the preset range, after a first preset time delay (e.g., but not limited to 3 seconds), the retractable mechanism is controlled to retract the lamp head assembly to a preset retracted position. Specifically, it retracts from its current first preset position to the preset retracted position, putting the lamp head assembly in a retracted state and turning it off so that it is not illuminated.

[0113] In one embodiment of the present invention, under different taillight intelligent welcome modes, the lamp head assembly is controlled to form different shapes by means of a retractable mechanism and a flip cover. This includes: in the third taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to extend to a second preset position at a third preset speed or to keep the lamp head assembly at a second preset position, and driving the flip cover to open to a first preset angle, and controlling the lamp head assembly to gradually light up to a preset target brightness according to a preset brightness increase rate, wherein the second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than or equal to the distance between the first preset position and the preset retraction position.

[0114] In a specific embodiment, the third preset speed is a pre-set speed value, which can be set according to actual needs. The setting is based on the speed at which the indicator light head assembly extends from its current position to the second preset position. That is, when the light head assembly is driven to extend or retract at the third preset speed, it is considered that the light head assembly is extending or retracting slowly. Furthermore, when the retractable mechanism drives the light head assembly to extend from its current position to the second preset position at the third preset speed, it is considered that the light head assembly is extending slowly to the second preset position. In a specific example, the third preset speed is less than the first preset speed and the second preset speed.

[0115] The preset brightness increase rate gradually changes to a pre-defined rate of change, which can be set according to actual needs. The setting is based on the speed at which the brightness of the indicator light head component increases when it is illuminated. That is, when the indicator light head component is illuminated according to the preset brightness increase rate, it is considered that the indicator light head component is gradually illuminating. Furthermore, when the indicator light head component gradually illuminates to the preset target brightness according to the preset brightness increase rate, it is considered that the indicator light head component has gradually illuminated to the preset target brightness. The preset target brightness is a pre-set brightness value. When the indicator light head component is outputting the preset target brightness, the light output brightness is considered to be moderate, easily accepted by the user, and provides a comfortable experience.

[0116] That is, when entering the third taillight intelligent welcome mode, which corresponds to the taillight intelligent welcome mode activated by opening the tailgate, if the current position is different from the second preset position, the retractable mechanism is controlled to drive the lamp head assembly slowly from the current position to the second preset position, and the flip cover is driven to open to the first preset angle to maximize or mostly expose the lamp head assembly. The first preset angle is, for example, the maximum opening angle of the flip cover, such as 12.5 degrees. At this time, the flip cover is fully open, no longer obstructing the lamp head assembly, thus maximizing its exposure. If the current position is the same as the second preset position, the retractable mechanism is controlled to keep the lamp head assembly in the current position, i.e., in the second preset position, and the flip cover is driven to open to the first preset angle to maximize or mostly expose the lamp head assembly. The first preset angle is, for example, the maximum opening angle of the flip cover, such as 12.5 degrees. At this time, the flip cover is fully open, no longer obstructing the lamp head assembly, thus maximizing its exposure. Furthermore, the lamp head assembly is gradually brightened to a more comfortable brightness, i.e., the preset target brightness.

[0117] The second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than or equal to the distance between the first preset position and the preset retraction position. The preset retraction position is the position corresponding to the lamp head assembly in the retracted state or the limit position to which the lamp head assembly can retract. The first preset position is a pre-set gear, which can be set to the first, second, or third gear in the lamp head assembly's extension / retraction path. The positions corresponding to the first, second, and third gears are located on the same side of the preset retraction position, and the distance between the position corresponding to the second gear and the preset retraction position is greater than the distance between the position corresponding to the first gear and the preset retraction position, and the distance between the position corresponding to the third gear and the preset retraction position is greater than the distance between the position corresponding to the second gear and the preset retraction position. The opening and closing of the flip cover can be controlled according to the first preset position. Specifically, when the telescopic mechanism is in the first preset position, the flip cover is closed to cover or hide most of the lamp head assembly, exposing only a small part of the front of the lamp head assembly, i.e., the initial exposed part when it is in the retracted state. When the first preset position is the position corresponding to the second position, the telescopic mechanism is in the second preset position to partially open the flip cover, such as opening it 7 degrees, so that the flip cover covers a small part of the lamp head assembly and exposes most of the lamp head assembly, thus partially hiding the taillight. When the first preset position is the position corresponding to the third preset position, the telescopic mechanism is in the third preset position to fully open the flip cover, such as opening it 12.5 degrees, so that the flip cover no longer covers the lamp head assembly, allowing the lamp head assembly to be exposed to the maximum extent.

[0118] The second preset position is, for example, the maximum extension position of the lamp head assembly, which corresponds to the position when the taillight is extended to the 3rd position. At this time, the flip cover is fully opened, such as 12.5 degrees, so that the flip cover no longer blocks the lamp head assembly and the taillight can be exposed to the maximum extent.

[0119] Specifically, when entering the third taillight intelligent welcome mode, which corresponds to the taillight intelligent welcome mode activated by opening the tailgate, since users usually open the tailgate manually or by kicking it, and the user is relatively close to the tailgate at this time, the light head assembly can be extended to the maximum extension position, such as the third position, and the light head assembly can be lit to a comfortable brightness to improve the user's visual comfort. This fully demonstrates the dynamic deformation effect of the light head assembly, thereby improving the vehicle's welcome effect, enhancing the overall sense of technology and intelligence of the vehicle, and improving the user's driving experience.

[0120] In a specific embodiment, the second preset position is, for example, the position corresponding to the third gear. In the third taillight intelligent welcome mode, if the lamp head assembly is not currently in the third gear position, the telescopic mechanism can be controlled to drive the lamp head assembly to slowly extend to the third gear position. If the assembly is already in the third gear position, the lamp head assembly is driven to remain in the third gear position. That is to say, the lamp head assembly is driven to slowly deform to the third gear position, and the lamp head assembly is controlled to gradually illuminate to a more comfortable preset target brightness, and the flip cover is controlled to fully open, such as opening to 12.5 degrees, to maximize the exposure of the lamp head assembly, thereby fully demonstrating the dynamic deformation effect of the lamp head assembly, thereby improving the vehicle's welcome effect, enhancing the overall vehicle's technological and intelligent feel, and improving the user's driving experience.

[0121] In one embodiment of the present invention, in the third taillight intelligent welcome mode, the method further includes: when a vehicle tailgate locking signal is detected, controlling the retractable mechanism to drive the lamp head assembly to retract to a third preset position and driving the flip cover to be in a closed state; after a second preset time delay, controlling the retractable mechanism to drive the lamp head assembly to retract to a preset retraction position and turning off the lamp head assembly.

[0122] Specifically, after entering the third taillight intelligent welcome mode, if a tailgate locking signal is detected, indicating the tailgate is closed, and it is assumed the owner is about to leave, the third taillight intelligent welcome mode is exited, effectively disabling the taillight welcome function. When the tailgate is detected as closed, the retractable mechanism is first controlled to retract the lamp assembly from the current second preset position (corresponding to the third position) to the third preset position (corresponding to the first position), and the flip cover is kept closed to cover or hide most of the lamp assembly, exposing only a small portion of the front section. After the lamp assembly retracts to the third preset position, after a second preset time delay (e.g., but not limited to 3 seconds), the retractable mechanism is controlled to retract the lamp assembly to the preset retracted position, from the first position, putting the lamp assembly in a retracted state and turning it off.

[0123] In one embodiment of the present invention, when both a second type of welcome signal and a third type of welcome signal are received simultaneously, the vehicle is prioritized to enter the second taillight intelligent welcome mode. After the second taillight intelligent mode is completed, the vehicle is then prioritized to enter the third taillight intelligent welcome mode. In other words, the second taillight intelligent welcome mode has a higher priority than the third taillight intelligent welcome mode. When both a welcome signal indicating the car key is near the tailgate and a welcome signal indicating the tailgate is open are detected simultaneously, the second taillight intelligent welcome mode corresponding to the car key near the tailgate is executed first. After the third taillight intelligent welcome mode is completed, the third taillight intelligent welcome mode corresponding to the tailgate being open is then executed.

[0124] In one embodiment of the present invention, the method for controlling vehicle taillights further includes: receiving a taillight off control command input by a user through a taillight control switch; responding to the taillight off control command, controlling the vehicle to exit the current taillight intelligent welcome mode, so as to control the flip cover to be in a closed state, and controlling the retractable mechanism to drive the lamp head assembly to retract to a preset retracted position or controlling the lamp head assembly to remain in the preset retracted position.

[0125] Specifically, the vehicle is equipped with a taillight control switch for manual operation by the user. Users can control the taillights manually by activating this switch. The taillight control switch can be a physical switch or button located inside the vehicle, or a virtual switch or button on a user terminal linked to the vehicle, such as a mobile phone. The taillight control switch inside the vehicle can be located on the center console for convenient user operation. Specifically, users can decide whether to manually turn off the taillights based on actual working conditions to ensure taillight safety. For example, if a user believes that the current working conditions pose a safety hazard and are not suitable for activating the intelligent taillight welcome mode, the user can input a taillight off command through the taillight control switch. The taillight controller responds to the taillight off control command, controls the vehicle to exit the current intelligent taillight welcome mode, controls the flip cover to be in the closed state, and controls the retractable mechanism to drive the lamp head assembly to retract to the preset retractable position when the taillights are not in the preset retractable position, or drives the lamp head assembly to remain in the preset retractable position when the taillights are already in the preset retractable position, thereby forcibly turning off the intelligent taillight control and forcibly retracting the taillights to the preset retractable position, thus ensuring taillight safety.

[0126] In one embodiment of the present invention, the control method for the vehicle taillights further includes displaying the real-time status of the taillights. For example, the real-time status of the taillights can be displayed through a display module, such as a vehicle dashboard or a HUT (Head Unit, terminal information display unit), including whether the taillights are currently in a preset retractable position, in position 1 (in a first preset position with the flip cover closed), position 2 (in a second preset position with the flip cover partially open), or position 3 (in a third preset position with the flip cover fully open), as well as the current brightness of the taillights, so that the user can promptly know the real-time status of the taillights. Furthermore, when a taillight malfunctions, the real-time display status of the taillights can also provide a basis for fault repair, facilitating timely and accurate repair by maintenance personnel. In specific embodiments, the real-time status of the taillights can be displayed in the form of, but not limited to, images, text, videos, or three-dimensional simulation images.

[0127] To facilitate a better understanding of the present invention, the following is combined with... Figure 8 The following describes in detail the vehicle taillight control method of the present invention using specific embodiments.

[0128] In this embodiment, the control execution body of the vehicle taillight control method is, for example, the vehicle taillight controller, that is, the taillight controller controls the telescopic mechanism and the flip cover action, thereby realizing the control of the shape of the lamp head assembly.

[0129] Specifically, such as Figure 8 As shown, the method for controlling the vehicle's taillights includes the following steps:

[0130] Step S10: Process begins.

[0131] Step S11: Determine whether the taillight welcome mode switch of the vehicle has been set, that is, determine whether the vehicle has a welcome function. If yes, it means that the taillight welcome mode switch has been set and the vehicle has a welcome function. Then the taillight controller is awakened and enters the working state. Determine the type of welcome signal, so as to control the vehicle to enter different taillight intelligent welcome modes according to the type of welcome signal. Specifically, if it can be executed, execute step S13, step S15 or step S19. Otherwise, execute step S12.

[0132] Step S12: If it is determined that the taillight welcome mode switch is not set, that is, the vehicle does not have the welcome function, the taillight controller will go into sleep mode and not work, and the taillights will not move.

[0133] Step S13: The vehicle is detected to be unlocked, and the intelligent welcome mode of the first taillight is entered, and step S14 is executed.

[0134] Step S14: Control the lamp head assembly to quickly extend and retract twice between the preset retraction position and the set gear, accompanied by flashing lights. The set gear is gear 1, gear 2, or gear 3.

[0135] Step S15: The car key is detected to be close to the tailgate and within a preset range from the tailgate. The second taillight intelligent welcome mode is activated, and step S16 is executed.

[0136] Step S16: Control the lamp head assembly to quickly extend and retract twice between the preset retraction position and the set level, and finally stop at the set level, accompanied by flashing lights. The set level is level 1, level 2, or level 3. Then, proceed to step S17.

[0137] Step S17: Detect ambient light signal. If it is determined to be daytime, control the light component to remain off. If it is determined to be nighttime or in dim light, control the lamp head component to turn on. Then, proceed to step S18.

[0138] Step S18: If the car key is detected to be moving away from the tailgate, and it moves away from the preset range of the tailgate, the taillights will be retracted after a 3-second delay, i.e., retracted to the preset retraction position, and the headlight assembly will not be illuminated, i.e., the lights will be turned off.

[0139] Step S19: If the tailgate is detected to be unlocked, i.e. the tailgate is opened, then enter the intelligent welcome mode of the third taillight and specifically execute step S20.

[0140] Step S20: Control the taillights to slowly operate to the 3rd gear, and gradually brighten the lights to a more comfortable preset target brightness. Then, proceed to step S21.

[0141] Step S21: If a tailgate locking signal is detected, i.e., the tailgate is closed, the headlight assembly is controlled to retract to position 1. Then, proceed to step S22.

[0142] Step S22: After a 3-second delay, control the taillights to retract to the preset retraction position, and control the headlight assembly to turn off, i.e., turn off the lights.

[0143] Therefore, in this embodiment, the taillight controller can control the vehicle to enter different taillight intelligent welcome modes according to different welcome signals. Then, according to different taillight intelligent welcome modes, it controls the lamp head assembly to dynamically deform to form different shapes. For example, the taillight can be extended to different positions through a telescopic mechanism, and the area of ​​the lamp head assembly can be adjusted by flipping the cover to dynamically change the hidden area of ​​the lamp head assembly. This enables the taillight to achieve a cool and transforming welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0144] According to the vehicle taillight control method of the present invention, by receiving the vehicle's welcome signal and determining the type of the welcome signal, the vehicle is controlled to enter different taillight intelligent welcome modes according to different welcome signal types. Then, according to different taillight intelligent welcome modes, the lamp head assembly is controlled to dynamically deform to form different shapes. For example, the taillight can be extended to different positions by a telescopic mechanism, and the area of ​​the lamp head assembly can be adjusted by flipping the cover plate to dynamically change the hidden area of ​​the lamp head assembly. This enables the taillight to achieve a cool and deformable welcome function, improving the vehicle's intelligence and technological feel, and enhancing the user's driving experience.

[0145] A further embodiment of the present invention discloses a control device for a vehicle taillight. As described above, the taillight includes a lamp head assembly, a telescopic mechanism, and a flip cover. The telescopic mechanism is used to drive the lamp head assembly to extend and retract. The flip cover is disposed on the lamp head assembly to adjust the shading area of ​​the lamp head assembly when the flip cover is opened or closed.

[0146] Figure 9 This is a structural block diagram of a vehicle taillight control device according to an embodiment of the present invention, such as... Figure 9 As shown, the control device 1000 for the vehicle taillights includes: a receiving module 1001, a determining module 1002, and a control module 1003.

[0147] Specifically, the receiving module 1001 is used to receive the vehicle's welcome signal.

[0148] The determination module 1002 is used to determine the type of welcoming signal.

[0149] The control module 1003 is used to control the vehicle to enter different taillight intelligent welcome modes according to the type of welcome signal, and to control the lamp head assembly to form different shapes according to different taillight intelligent welcome modes through the telescopic mechanism and the flip cover.

[0150] In one embodiment of the present invention, the determining module 1002 determines the type of the welcome signal, including: when a vehicle unlocking signal is detected, determining the welcome signal as a first type of welcome signal; and / or when a key signal of the vehicle is detected within a preset range of the vehicle tailgate, determining the welcome signal as a second type of welcome signal; and / or when a vehicle tailgate unlocking signal is detected, determining the welcome signal as a third type of welcome signal.

[0151] In one embodiment of the present invention, the control module 1003 controls the vehicle to enter different taillight intelligent welcome modes according to the type of welcome signal, including: when the welcome signal is determined to be a first type of welcome signal, controlling the vehicle to enter a first taillight intelligent welcome mode; when the welcome signal is determined to be a second type of welcome signal, controlling the vehicle to enter a second taillight intelligent welcome mode; and when the welcome signal is determined to be a third type of welcome signal, controlling the vehicle to enter a third taillight intelligent welcome mode.

[0152] In one embodiment of the present invention, the control module 1003 controls the lamp head assembly to form different shapes through a retractable mechanism and a flip cover in different taillight intelligent welcome modes. This includes: in the first taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to perform a first retraction action a first preset number of times to drive the flip cover to close or open, and controlling the lamp head assembly to flash at a preset frequency during the execution of the first retraction action a first preset number of times; wherein, the first retraction action includes: the lamp head assembly extending from a preset retractable position to a first preset position at a first preset speed, and then retracting from the first preset position to the preset retractable position.

[0153] In one embodiment of the present invention, the control module 1003 controls the lamp head assembly to form different shapes through a retractable mechanism and a flip cover in different taillight intelligent welcome modes. This includes: in the second taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to perform a second retraction action a second preset number of times to drive the flip cover to close or open; and after performing the second retraction action, controlling the lamp head assembly to move to a first preset position; and during the execution of the second retraction action a second preset number of times and the control of the lamp head assembly to move to the first preset position, controlling the lamp head assembly to flash at a preset frequency; wherein the second retraction action includes: the lamp head assembly extending from a preset retractable position to the first preset position at a second preset speed, and then retracting from the first preset position to the preset retractable position.

[0154] In one embodiment of the present invention, after the control module 1003 performs the second extension action and controls the lamp head assembly to run to the first preset position, it is further configured to: acquire the ambient light brightness; when the ambient light brightness is greater than a preset brightness threshold, control the lamp head assembly not to light up; when the ambient light brightness is less than or equal to the preset brightness threshold, control the lamp head assembly to light up.

[0155] In one embodiment of the present invention, the control module 1003, in the second taillight intelligent welcome mode, is further configured to: when the key signal of the vehicle is detected to be outside the preset range of the vehicle tailgate, delay for a first preset time, control the retractable mechanism to drive the lamp head assembly to retract to the preset retraction position, and turn off the lamp head assembly.

[0156] In one embodiment of the present invention, the control module 1003 controls the lamp head assembly to form different shapes through a retractable mechanism and a flip cover in different taillight intelligent welcome modes. This includes: in the third taillight intelligent welcome mode, controlling the retractable mechanism to drive the lamp head assembly to extend to a second preset position at a third preset speed or to keep the lamp head assembly at the second preset position, and driving the flip cover to open to a first preset angle; and controlling the lamp head assembly to gradually light up to a preset target brightness according to a preset brightness increase rate, wherein the second preset position and the first preset position are located on the same side of the preset retraction position, and the distance between the second preset position and the preset retraction position is greater than or equal to the distance between the first preset position and the preset retraction position.

[0160] In a specific embodiment of the present invention, the control module 1003 is configured, for example, as a taillight controller for a vehicle.

[0161] In one embodiment of the present invention, the control device 1000 for the vehicle taillights further includes a display module (not shown in the figure), which is used to display the real-time status of the taillights.
